Yet that is exactly where it brought me. For decades, planetary scientists have believed that the early solar system was enriched with short-lived radioactive elements —such as aluminum-26—by a nearby ...

NASA and University of Arizona researchers have discovered pristine mineral grains that formed in an ancient supernova explosion. The grains were among other extraterrestrial dust plucked by ...

Around 11,300 years ago, a massive star teetered on the precipice of annihilation. It pulsed with energy as it expelled its outer layers, shedding the material into space. Eventually it exploded as a ...

Ion probe studies and improved stellar nucleosynthesis models are providing new insights into our solar system's stardust Until recently, cosmochemists and astrophysicists assumed that supernovae and ...

A joint NASA-JAXA mission has revealed rare elements in a supernova. XRISM detected life-essential elements in Cassiopeia A. These discoveries shed new light on how stars create cosmic chemistry.

Using ESA’s Integral observatory, an international team of researchers has been able to confirm the production of radioactive aluminium (Al 26) in massive stars and supernovae throughout our galaxy ...

(Nanowerk News) Until recently, cosmochemists and astrophysicists assumed that supernovae and their progenitors, the supergiant stars, contributed only little of our solar system’s stardust content.
